SCOTTSDALE — Jhoulys Chacin’s smooth spring hit a speed bump Thursday when he left after three innings with a blister on his right index finger. He threw only 44 pitches.

Chacin said the injury will not place his next start on Tuesday in jeopardy.

“It’s nothing bad,” he said. “I’m going to make my next start. They wanted to play it safe.”

Chacin has allowed just two runs in eight innings this spring.

The right-hander reached just 90 mph on his fastball during his three innings today, leaving some scouts to wonder if he had hit a “dead arm” period of camp. However, he said he could not grip his fastball because he broke a fingernail during warm-up that affected his fastball and created the blister.

“I was trying to grab the ball differently. It looked really bad when I came out of the game,” Chacin said. “They just popped it and got all the blood out, and put something to get it hard and tomorrow we will see how it feels.”

Chacin admitted that he has suffered blister issues before when he has cut his fingernail too short. Because it’s still early in spring, it’s possible the Rockies will move Chacin’s next start back as they did with Drew Pomeranz. With tightness in his right glute, Pomeranz saw his next game bumped from Sunday to Wednesday.

The Rockies are counting heavily on Chacin to deliver a breakout season. He was just 3-10 with a 4.58 ERA from June 27 on last season.
